Iteration 2: Speculate

Plan for Iteration 2.

Minimum Viable Product (MVP): When Gaitkeeper can accurately sense a normal walking gait and provide recognizable feedback when the gait is improper. This will include an accelerometer whose reading will be processed in a program to determine walking gait and in turn vibrate the user to notify them that the gait is improper.

Total Feature List (prioritized):

Feature	Priority	Time
Detect walking with accelerometer	High	65 hours
Research walking gait and angles associated at various steps	High	20 hours
Use potentiometer and bend sensor to test ROM	Medium	10 hours
Use switch on brace or pressure sensor hinge to detect full extension	Low	10 hours
Learn how to use Arduino Nano BLE function	Medium	6 hours
Use BLE/wifi to send data to computer for sensing buzzer	High	30 hours
Integrate walking data with computer readings to activate buzzer	High	20 hours
Use data on computer to do data analysis for user and PT	Low	25 hours
Test various batteries (9V, portable phone charger)	Medium	5 hours
Test and determine best feedback mechanisms (buzzer, haptic, etc)	High	10 hours
Attach and adjust placement of sensors on brace	Medium	5 hours
———————————————————-	——-	TOTAL: 216 hours

Work planned for iteration 2:

Name	Feature	Hours
Mallory	Swap out potentiometer, incorporate another buzzer, detect walking with accelerometer	~24 hours
Elsy	Swap out potentiometer, incorporate another buzzer, detect walking with accelerometer	~24 hours
Elijah	Swap out potentiometer, incorporate another buzzer, detect walking with accelerometer	~24 hours

The desired outcome of iteration 2 is a fully functioning prototype (our MVP) where walking is properly detected. We would like the brace to have all the new components we decided upon connected and to detect the walking motion properly. This will include replacing our current components with refined ones and using our conceptual gait research in practice.
